1 Precautions

Follow these safety and servicing precautions to prevent damage and to protect against potential hazardssuch as electrical shock and X-rays.

1-1 Safety Precautions

1-1-1 Warnings

1. For safety purpose, do not attempt to modifythe circuit board, and always disconnect the ACpower before performing servicing on themonitor.

2. Operation of the monitor outside its cabinet orwith the cover removed involves the risk ofshock hazard. Repair work on the monitorshould only be attempted by service personnelwho are thoroughly familiar with all necessarysafety precautions and procedures for workingon high voltage equipment.

3. Do not lift the CRT by the neck. Aftercompletely discharging the high voltage anode,handle the CRT only when wearing shatterproofgoggles. Try to keep the CRT away from thebody during handling.

4. High voltage should always be kept at the ratedvalue, no higher. Only when high voltage isexcessive are X-rays capable of penetrating theshell of the CRT. Operation at high voltagesmay also cause failure of the CRT or highvoltage circuitry.

5. The CRT is especially constructed to limit X-ray emission to 0.5mR/HR at 300 microamperesanode current. To ensure continued X-rayprotection, replace the CRT with only the sameor equivalent type as the original, and adjust theanodes voltage to the designated maximumrating, never to exceed.

1-1-2 Safety Checks

Before returning the monitor to the user, performthe following safety checks:

1. Inspect to make certain that each lead dress isnot pinched or that hardware is not lodgedbetween the chassis and other metal parts inthe monitor.

2. Inspect all protective devices such as

nonmetallic control knobs, insulating materials,cabinet backs, adjustment and compartmentcovers or shields, isolation resistor-capacitornetworks, mechanical insulators, etc.

3. AC Leakage Current Check

Always perform the AC Leakage CurrentCheck on the exposed metal parts, includingmetal cabinets, screwheads and control shafts,as follows:

a) Plug the AC line cord directly into a ratedAC outlet. Do not use an isolationtransformer during the check.

b) Use an AC voltmeter with at least 5000ohms per volt sensitivity as follows:

Connect a 1500 ohms, 10 watt resistorparalleled by a 0.15uF AC capacitor in serieswith all exposed metal cabinet parts and aknown earth ground, such as electricalconduct or electrical ground connected toearth ground, as shown in the Figure 1-1.Measure the AC voltage across thecombination of resistor and capacitor.

c) Reverse the AC plug at the AC outlet andrepeat the steps for AC voltagemeasurements for each exposed metal part.

d) Voltage reading must not exceed 0.3 voltsRMS, equivalent to 0.2 milliampere AC. Anyvalue exceeding this limit ill constitute apotential shock hazard and must becorrected immediately.

4-4 Power Supply Section

4-4-1 AC Rectifier

The circuit can accept 90 V to 264 V AC input through D801 bridge diodes and C808 filtering to get DC 126V~364 V for power conversion in T802.

4-4-2 Line Filter

It consists of C801, C802, C803, C816, C820, C823, T801, T804 and meets EMI regulation.

4-4-3 Power LED Status

1. The LED has 3 leads with common cathode to emit green and amber color light for different powersaving states.

2. Normal : Green light

3. Off Mode : Amber light

4-4-4 Auto Degaussing

When S801 turns on, pin 27 of I701 will send a signal to Q802 and turns on RL801 for degaussing. After 4seconds, it will turn off RL801 automatically.

4-4-5 PWM Control

1. Start Up

The I801 (KC3843B) gets power from R846, Q821, R849, R848, D826, D828, D822 and pin 7 voltagereaches 8 V for starting up. The I801 starts oscillation at 22 kHz, sawtooth on pin 4 and pin 6 output todrive Q803/T802. Once Q803 switching on, D806, C804 set up an 15 V to keep I801 working throughD821 auxiliary voltage.

2. Regulation

The DC O/P voltage is proportional to the auxiliary voltage, so I801 pin 2 senses the feedback voltagefrom the divider R802, R823, VR801 and R820 to compare with the built-in 2.5 volts reference voltage forerror amplifier operation. Finally pin 6 can modulate the different duty cycle by VR801 setting to achieveregulation purpose.

C1996PNST

AC901Page 14

4-4-6 Synchronization

1. Normal Mode

The sync pulse from FBT (31 kHz~95 kHz) via R812, R831, C815, R826, D824, C814 and R816 to pin 4of I801 to keep I801 synchronized with horizontal sync input frequency.

2. Power Saving Modes: Off mode

Because there is no pulse from FBT, so the free-run frequency is decided by R817 and C814 and theSMPS works at 22 kHz.

3. Override

The horizontal free run frequency is about 62.5 kHz under override condition, SMPS is synchronized tothis frequency.

4-4-7 O.V.P.

If the auxiliary voltage is higher than zener voltage ZD807 (20 volts) and makes pin 3 of I801 higher than

1 V, pin 6 duty cycle is limited to have the OVP activated.

4-4-8 O.P.P.

The excess current of T802 through R813, R814, R834, C813, R865 and R864 can develop enough voltageon pin 3 then limit the power delivered because the pin 6 duty cycle is limited too.

4-4-9 High Voltage Generation with F.B.T.

1. The H. V generation circuit combines T101 F.B.T. with I101 TL494/KA7500 PWM control circuit.

2. When I101, Vcc(pin12) reaches at 12V, pin 5,6 gets a freerun sawtooth waveform about 25KHz, andapproximately 5.7Vp-p, when voltahe at pin 15 is higher than pin 16 (5V reference) then release pin 3 tobe controlled by pin 1 feedback signal and compare with pin 5 to output PWM.

3. HFLB1 is used to trigger pin 5 via Q112, to synchronize the deflection circuit.

4. PWM output will drive Q116 & T101 to gererate high voltage (26KV), T101 pin 11, 15 becomes DC/ACfeedback, with the voltage link to I101 non-inverting input pin 1 to stabilize H.V (26KV) and VR101 canbe adjusted to control H.V value.

5. When X.R.P occur, the hunlock will keep high to pull down I101 pin 2 and shut down PWM output.

4-5 Video Amplifier Section

1. RGB signal inputs are terminated by R501, R531 and R561 then pass through the coupling capacitorsC501, C531 and C561 to IC501 LM1267 preamplifier.

2. The amplifier RGB signals (0~4 Vpp) are adjusted by I2C bus from I501, pin 23 is for clamp pulse whichcomes from pin 16 of TDA4841.

3. The video output stages are amplified by I901(LM2465). The RGB cathodes cut off are adjusted by I2Cbus control by internal icon.

4. Under override condition, CHECK SIGNAL will show up on the screen.

4-6 OSD (On Screen Display) Circuit

C1996PNST

AC901 Page 15

1. The I502 NT6827-00002 is OSD IC. The OSD signals are worked by positive vertical pulse from I701 pin32 that goes through R554 to I502 pin 10, and positive horizontal pulse from HFLB1 through R527 to I502pin 5. CPU I701 pin 27, 28 (I2C bus) transfers information to I502 pin 7, 8.

2. The OSD R. G. B signals and blanking signal are terminated at I502 pin 15, 14, 13, and 12 feed into I501pin 1,2,3, and 4, then the OSD picture appears.

5-2-6 Degaussing

Degaussing is required when poor color impurity appears on the screen. This monitor uses an automaticdegaussing circuit that is activated when the power is on. The automatic degaussing will be fully functionalagain after the monitor has been in operation for 20 minutes.

The degaussing effect is confined to the picture tube since the coils are mounted at the back of the tube.Should any part of the chassis or cabinet becomes magnetized, it is necessary to degauss the affected areawith a manual degaussing coil.

5-2-7 Manual Degaussing

1. Apply line voltage to the degaussing coil and move it in a rotary motion over the front, sides, and top of themonitor. The coil should be kept away from the rear of the monitor to avoid damaging the magnetic neckcomponents.

2. Slowly rotate and move the coil away from the monitor to about 6 feet beyond the point where no effecton the CRT will be noticeable.

For proper degaussing, it is essential that the field be gradually reduced by moving the coil slowly away fromthe monitor. The degaussing coil must never be shut off or disconnected while near the monitor, as this wouldintroduce a strong field instead of canceling the effect of the stray fields.
